As a schoolboy, Farrant was a member of a short-lived new wave group called Safreak - a name that was culled from a half-erased piece of graffiti. After leaving Safreak, Farrant formed a band called Burning Hearts, which appeared in a "Battle of the Bands" style competition on BBC television's Going Live.
Farrant also plays guitar, bass, keyboards and other musical instruments. Farrant has also played drums for The Alarm, Spear of Destiny, Bad Manners and Grand National. According to Buzzcocks singer Pete Shelley, Farrant learned thirty songs in two days when he joined the band.
